Product Description:

The CH063C-13-3105 is a direct-drive rotary motor manufactured by Kollmorgen in the Cartridge DDR Motors series. As a cartridge-style unit, it mounts directly to a machine shaft and eliminates the compliance associated with mechanical transmissions, delivering position accuracy and high torque for indexing tables, packaging stations, and semiconductor tooling. It converts three-phase AC power into electromagnetic torque for use in closed-loop servo systems.

The motor accepts a supply of 400/480 VAC, and its windings draw up to 28.5 Arms during peak events. At this current, the motor can generate a peak torque of 157 Nm, which supports short acceleration bursts without saturation. Continuous operation at 400 V is characterized by a rated power of 6.14 kW and a synchronous speed of 950 rpm, while the standstill current remains at 11.3 Arms for holding static loads. The 10-pole design produces an electrical frequency compatible with common servo drives, and the winding resistance of 1.45 ohms limits copper loss under steady load. A winding inductance of 7.1 mH influences current rise time so the drive can regulate current smoothly. A voltage constant of 334 mV·min indicates the back electromotive force that the controller must overcome during rotation.

When powered at 480 V, the motor reaches 1150 rpm and delivers 7.44 kW without exceeding its thermal limits. Rotational response is influenced by a rotor inertia of 157 kg·cm², balancing quick indexing with stable velocity control. For static holding, the electromagnetic structure produces 61.8 Nm of standstill torque. A torque constant of 5.52 Nm/A allows the control system to calculate motor output from the commanded current. The 29 kg assembly has less mechanical complexity than a comparable gear-driven arrangement. Its mass also provides thermal capacity for continuous operating cycles.
